Several experiments were conducted to show that knowledge of the spelling of words is involved in making decisions about how they are pronounced. The experiments used a lexical decision task with only spoken words and nonwords. Subjects in each experiment heard an uninterrupted list of spoken words and nonwords at a rate of about one item every…

The status and progress of several studies dealing with the nature of speech, instrumentation for its investigation, and instrumentation for practical applications is reported on. The period of January 1 through June 30, 1969 is covered. Extended reports and manuscripts cover the following topics: programing for the Glace-Holmes synthesizer,…

GRADES OR AGES: Four-, five-, and six-year olds. SUBJECT MATTER: Sensory experiences, including tactile, auditory, and visual. ORGANIZATION AND PHYSICAL APPEARANCE: The guide is divided into three sections, one for each of the above sensory areas. Each section lists materials and describes activities; illustrations are interspersed. The guide is…

The Vicens-Reddy System is unique in the sense that it approaches the problem of speech recognition as a whole, rather than treating particular aspects of the problems as in previous attempts. For example, where earlier systems treated only segmentation of speech into phoneme groups, or detected phonemes in a given context, the Vicens-Reddy System…

Recent theories of verbal memory have hypothesized that memory for a stimulus is not represented by a unitary memory trace, but rather by a coding on several attributes of the event. The present experiment tested the differential forgetting hypothesis in a unique way. Words were presented either visually (V) or auditorally (A) in a continuous…

Reported were studies measuring residual auditory capacities of deaf persons and investigating hearing aids which transpose speech to lower frequencies where deaf persons may have better hearing. Studies on temporal and frequency discrimination indicated that the duration of a signal may have a differential effect on its detectability by…

Reported were estimates of hearing levels of noninstitutionalized children aged 6 to 11 years in the United States in relation to their demographic and socioeconomic background. Findings are results of individual monaural pure-tone air-conduction audiometric tests, conducted as part of the Health Examination Survey of 1963-65. In the survey 7,119…

The auditory perception skills of 32 learning disabled (LD) and 32 non LD culturally different elementary pupils were compared. Results of the Wepman Auditory Discrimination Test and three subtests of the Illinois Test of Psycholinguistic Abilities indicated consistent differences between the two groups on all four measures of auditory perception…

Investigates the principles underlying the perception of vowel stimuli. The results support Chistovich's claim. When judging the distance between synthetic vowel stimuli, speakers refer to the phonemic structure of their native language. They determine the phonemes closest to the stimuli and then compare the phonemes and not the stimuli…

Recently, Nilsson (1975) challenged Watkins's conclusion that the modality effect is a post-categorical phenomenon. In this brief reply the authors argued that Nilsson's findings are not only consistent with the postcategorical interpretation but also inconsistent with the precategorical interpretation.

An examination of the hearing mechanism and some of the factors involved in helping problems may offer encouragement for a regular schedule of hearing maintenance. It may also help music educators to become more aware and understanding of their own and students' hearing as it affects musical behavior. (Author)

The study determined whether eight undergraduate normal listeners, presented with filtered speech, would produce consonant confusions similar to those previously reported for the hearing-impaired listener. (Author/SBH)

Research by Posner and Mitchell (1967) was used to investigate levels of noise processing in testing subjects' ability to "gate out" the processing of irrelevant and unwanted material. Three experiments are reported in which subjects had to judge whether two letters were the "same" or "different". Noise elements were included to test attention…
